Context: The dynamics of anti-phospholipase A2 antibody titers during treatment could predict clinical responses in patients with membranous nephropathy.
Objectives: We analyzed the predictive value of the dynamics of these antibodies on clinical responses.
Materials and methods: The serum antibody levels were measured before and during treatment in 79 patients with anti-phospholipase A2 receptor antibody membranous nephropathy treated with two different immunosuppression regimens
Results: In both groups of patients, the relative reduction in antibody titers at 3 and 6 months preceded and predicted the clinical responses.
Conclusions: Antibody titer dynamics was useful for predicting clinical responses.
